I'm starting a new thread that features real-world, user-reported Prius c mpg's since many of you asked specifically about them and the original thread was moving a bit off topic. I've included mpg reports that were in my previous post -- sorry, I haven't had opportunities for any new mpg tests. As new owners start driving, they can add their reports here. Seems like most people want to know factors that can affect the results, e.g. the total length of the trip, terrain, weather, surface streets vs. freeway, trying to conserve gas vs. regular driving, no. of passengers, etc. so please include whatever you can. Previously posted trip mpg info: - 12 mile freeway stretch and back using cruise control at 60mph in Eco Mode. Tailwinds of 15-25 mph going out, same headwinds coming back. Outside temp 80 degrees. Rolling hills and a gradual rise in elevation from sea level to 1100 feet and back down to sea level; same thing on return 12-mile trip: high 40s mpg The following are surface street trips; the longer trips included a 5 mile stretch of "highway" (no stoplights) where the speed limit is 45 (but most people travel 55). Moderate to heavy commuter traffic. - 12 miles going up 1200 ft elevation and back down to sea level: 57.3 mpg - 4 miles uphill with relatively steep sections to 700 ft elevation: 27.3 mpg - 4 miles downhill (same as above coming down) in heavy traffic using EV for 95% of the trip: 99.9 mpg We thought the display was broken or stuck, but it must have meant it was over 100 mpg. - 17 miles up to 1200 ft, down to 200 ft, back up to 700 ft, down to sea level: 51.8 mpg Looking forward to seeing what everyone else posts!
